Injury and Repair - 1

This is a continuation of the previous experiment   in which a virus triggered  CA-3 injury. In order to repair the  damage CA-4 transferred its resources to CA-2.  Its  structure (receptor) changed so that the virus could no longer attach to it and trigger the injury.    Also the  present  proliferon was infected by a virus yet it lacked enough resources to change CA-2 structure. It applied therefore a different strategy for damage  repair.

The experiment started with three synchronous CA smaller than those in the previous one. Their size was determined by the set point >= 15.

Infection and injury

Whenever CA-2 reached state  15, five of the left most cells of CA-3 were set to zero (white). Following injury  CA-3 changed  and attempted  to regain its healthy structure. However whenever CA-2 reached its state=15, it hit CA-3 again and again. CA-4 was not affected.


The stem process (CA-1) continually compares the structures of  transitory processes. When detecting that CA-2 and  CA-3 differed, it  applied the repair strategy of the previous experiment . However since  the CA were small their resources did not suffice to change the CA-2 structure and CA-1 applied an alternative strategy. It drained the CA-3 resources until it became atrophic.

Idle process

CA-4 was idle.  It did not contribute its resources to CA-2 since they would not suffice to repair the injury. Even the resources of CA-3 together with CA-4 did not suffice to change CA-2 structure. The stem process initiated therefore CA-3 atrophy.


Perturbation poses a threat to the proliferon and it attempts to settle at a new solution. This can be achieved either by diverting resources between CA like in the previous experiment , or making a process atrophic  The two strategies enable the proliferon to  attain a solution  whatever the injury to CA-3.


The objective  of the present  study is to design a proliferon which will attain  a solution from any perturbation. In a previous experiment the perturbation was an excessive resource drainage. In the present experiment it is injury. In both instances the proliferon always attains a solution. By making CA-4 idle the proliferon solution was more optimal than if CA-4 would have participated in the repair. This optimizing capacity is called Wisdom of the Body (WOB). However the present solution is less favorable than that of the previous experiment since it does not confer immunity upon the proliferon. The next experiment will come up with a more optimal solution.
